Today GCC 11.1 was released, the first stable release of GCC 11.

Currently GCC gets installed using the gcc.sh installer script, using the versions in the toolset-2004.json and toolset-1804.json files. It uses the ubuntu-toolchain-r/test repository, which doesn't have gcc-11 available.

At this moment, a stable GCC 11 version is not yet available on either Ubuntu packages (so not for focal-updates) or Debian packages (only on experimental), which is where the complication starts.

Options to install GCC-11:

• Building from source
• Building once and caching/hosting somewhere
• Using experimental toolchain
• Waiting for package managers to update
• More?

Lets use this issue to discuss how GCC 11 can be installed best on the Ubuntu images.
